Florissant Fossil Beds National Monument
Florissant Fossil Beds National Monument preserves fossils from 34 million years ago at the site of the Eocene-era Lake Florissant, which was inundated with volcanic ash. The ash has preserved an amazing assortment of plants, fish, spiders, and insects whose fossil remains can be seen at the visitor center. You will also see huge petrified tree stumps. There are 14 miles of hiking trails there, most of them pretty easy and one fully accessible. Check with the Visitor Center to determine their condition and suitability for you.
The Monument has a non-motorized wheelchair with large, inflatable tires that can be requested and borrowed for daily use.”
